may have found a way to synthesize this behavior, using simple elements, not requiring Cerium.

this is the same reason why Hydrogen is both a Positive & Negative polarity, and how by understanding this will cure disease.

its the same reason Hydrogen is both Water & Oil soluble.

Cerium is a chemical element with the symbol Ce and atomic number 58.

Cerium is the second element in the lanthanide series, and while it often shows the oxidation state of +3 characteristic of the series, it also has a stable +4 state that does not oxidize water.

F-Block

Because of their complex electronic structure, the significant electron correlation effects, and the large relativistic contributions, the f-block elements are probably the most challenging group of elements for electronic structure theory.

The f-block, with the f standing for "fundamental" and azimuthal quantum number 3, appears as a footnote in a standard 18-column table but is located at the center-left of a 32-column full-width table. Periods from the sixth onwards have a place for fourteen f-block elements.

These elements are generally not considered part of any group. They are sometimes called inner transition metals because they provide a transition between the s-block and d-block in the 6th and 7th row (period), in the same way that the d-block transition metals provide a transitional bridge between the s-block and p-block in the 4th and 5th rows.
